Which one would each critic pick
| Critic | OpenFang | Supacode | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 5.5 | 6.0 | Supacode — Pick Supacode if you run several agents at once on a Mac and keep checking which one is stuck; pick a terminal multiplexer if you only ever run one. |
| El Crítico | 4.8 | 5.5 | Supacode — It knows what each agent is doing by installing hooks into that agent's own configuration, which makes the status display dependent on three other vendors not changing their hook format. |
| El Profesor | 5.3 | 6.8 | Supacode — Sessions run inside a separate session daemon rather than as children of the application, so the interface is a viewer over state that outlives it. |
| La Inversora | 5.3 | 4.8 | OpenFang — Eighteen thousand stars since February 2026 and no price of any kind, with twenty-six providers and forty channels standing in for a moat that is really an integration list. |
| La Jefa | 4.0 | 4.0 | no preference |
| El Hacker | 7.3 | 4.8 | OpenFang — Apache-2.0 Rust in a single binary, an MCP client and server on the same process, installed by curl, and no local model option, which is the one thing missing. |
